For those of you tracking trunk I've just checked in some shiny new features. The Snippet command will now give you a list of snippets defined in a buffer (big, big props to Ori for this patch) and I've created two commands to help you create your own snippets.
Check out the docs for CreateSnippet and CreateBundleSnippet.
No excuse for not submitting your own snippets now :-)
Oh, and this does mean that 1.2 will be coming out sooner than I thought.
